>> music first or electronics first?

They both come into play when you're reproducing sound.
I too don't like "the in your face" presentations too popular today.
The reason I got rid of my Jolida CD player and Sophia Baby.

First priority is choosing the right drivers to use.
If you get this wrong then everything else is doomed.
I chose drivers with a smooth roll-off so
that I could get away with no inductor.
Audax 5.25 and 4" Aerogels, HiVi D10G & Dynaudio D260
(Audax's in parallel-the 5.25 went low enough and
the 4" mated well with the Dynaudio D260 I tried them
in parallel just for laughs and it worked great)
I was lucky as I had these on hand from
prior attempts at speaker building.
I have only 1 cap per speaker for my crossover
to protect the expensive Dynaudio D260 tweeter.
Now choosing the cap is critical too -
voicing is everything - it's got to blend.
Voicing the speaker can make it in your face
or totally laid back - the choice is yours.
I had 4.7uFd Hovlands and it was in your face which
I thought was great but it soon started to get to me.
Replaced it with a 5uFd GE Oil w .1uFd Vit Q and
was much better but still had an edge to it.
About 2 hours ago I thought of putting a resistor
across the tweeter to attenuate it and increase the
crossover frequency and VOILA a magical presentation!!!
Open and spacious without the "in your face".

Second you need an amp that will drive it easily.
Again I had one laying around that fit the bill.
At least til my SE KT66 is finished.

And third you need the synergy of everything together.
Interconnects, speaker wire and electronics.

You can try active crossovers BUT (a big but here)
you need the drivers to be flat during the transition.
If not then you do have a big can of worms.
Here is were passives excel because you can have a first,
second or third order and mix and match with each
different impedance slope for the best response.
A variable not available when using active crossovers.
